Greatest common factor (GCF) explained - Khan Academy
WebFirst we find the prime factors of each number, using prime factorization. 30 = 2 × 3 × 5 45 = 3 × 3 × 5 Next, identify those prime factors that both numbers have in common, and multiply them. Here, both 3 and 5 are common factors. The GCF is 3 times 5, or 15. 3 × 5 = 15 <— GCF EXAMPLES Find the GCF of these pairs of numbers. 14, 49 Web94K views 11 years ago Solving Quadratic Equations by Factoring This video explains how to solve a quadratic equation by factoring out the greatest common factor.

WebIn order to find the greatest common factor of two given numbers, you need to find all the factors of both the numbers and then identify the common factors. Find out the GCF of 18 … WebMar 26, 2016 · A useful method for solving algebraic equations that contain negative exponents is to factor out a negative greatest common factor, or GCF. For example, consider the equation 3 x –3 – 5 x –2 = 0. This equation has a solution that you can find without switching to fractions right away. WebThe Greatest Common Factor, the GCF, is the biggest (that is, the "greatest") number that will divide into (that is, the largest number that is a factor of) both 2940 and 3150. In other words, it's the number that contains all the factors *common* to both numbers. In this case, the GCF is the product of all the factors that 2940 and 3150 share. incarnation\\u0027s 80
